5 in 1 dental implant method and apparatus

The present application claims priority to U.S. patent application Ser. No. 12/265,854, filed Nov. 6, 2008, entitled “DRILL FOR RAPID DENTAL IMPLANT”, to U.S. patent application Ser. No. 12/357,046, filed Jan. 1, 2009, entitled “IMPLANT ROOT FOR TOOTH IMPLANTING”, and U.S. patent application Ser. No. 11/564,911, filed Nov. 30, 2006, entitled “IMPLANT ROOT FOR TOOTH IMPLANTING”, the entire contents of each are incorporated herein by reference.

The present invention relates to dental procedures and equipment and more particularly, to a procedure and equipment for lifting a sinus membrane and applying bone graft to a nasal sinus.

Dental implants have become a preferred solution for resolving the problems caused by dentures. Dental implants are made of titanium metal that is of a highly biocompatible material, but does not disintegrate into bio-toxicity while being installed in human bodies. Therefore, the dental implants, with proper surgical procedures, can provide approximately a 90% success rate, as well as improve durability, aesthetics, biting force, prevention of bone loss, etc.

In general, a dental implant is a substitute itself for a lost natural tooth, or a dental operation, in which a screw shape fixture is secured to the jawbone and fused with the jawbone for a predetermined period of time, and then an abutment, i.e. a coupling part, and a prosthesis such as an artificial tooth crown are fixed to the fixture so as to restore the original function of a tooth.

A false tooth or crown is provided with a hole, known as a chimney, there through, and a non-round recess in its base that corresponds in shape to the protruding non-round cross-section of the abutment. Thereby, the crown can be joined to the abutment with a self-aligning connection that prevents relative rotation between them. A screw, passed into the chimney opening, engages the tapped hole in the abutment so as to hold the crown axially to the abutment. Thus, the crown cannot rotate about the abutment because it is fixed into the special contours on the exposed abutment end, and the crown cannot pull away from the abutment when the screw has been tightened in place. Finally, the chimney above the screw is filled with a composite filler material that hardens and is shaped as part of the crown, to look like a natural tooth.

During dental implant placement, an osteotomy is performed to make a proper size round hole on the crestal bone for the installation of an implant. During a conventional osteotomy, different sizes of drills are used to drill a cut hole. This may involve using a round bur for flattening an occlusal surface of the crestal bone and making a location mark for implant, then using a plurality of drills of different diameters to drill a cut hole smaller than the diameter of an implant (for example, if the diameter of an implant is 4.75 mm, the diameter of the drill is 4.25 mM.

After drilling of a cut hole with the plurality of different drills, a countersink drill is then conventionally used to drill the cut hole to the desired diameter equal to a threaded implant, and then a tap is used to tap a thread in the cut hole for the installation of the threaded implant in the crestal bone. Since this conventional cut hole drilling method requires different sizes of drills to be used, operation time and difficulty is increased, thereby lowering the operation success rate.

Furthermore, for posterior positions the sinus floor may be too thin to sufficiently support a conventional implant root. Prior approaches elevate the sinus floor involved creating a window by fracturing part of the skull to gain access to the maxillary sinus. Once the sinus was exposed, a surgeon would then take bone from a patient\'s hip and graft the bone to the sinus floor. This is considered a major surgery and is performed in a hospital setting under general anesthesia. Also, this process requires a lengthy healing period of 8-12 months. After 8-12 months, a second surgery is then performed to place one or more dental implants in the grafted sinus bone. Then, another 6-9 months is required for healing before final restorations may be placed.

The inventor of the present invention disclosed a dental implant implantation operation for allowing quick implantation of a dental implant without requiring multiple surgeries. To facilitate performance of this quick dental implant implantation operation, the inventor created a number of dental instruments including U.S. application Ser. No. 12/357,046, entitled “Improved implant root for tooth implanting”; U.S. application Ser. No. 12/265,854, entitled “Drill for rapid dental implant”; Taiwan Utility M313502, entitled “Adjustable double blade handle unit”; Taiwan Utility M313504, entitled “Hydraulic pressure type nasal sinus membrane separator”; U.S. application Ser. No. 12/265,012, entitled “Vibrational filling device implanting tooth bone powder”; Taiwan Utility M313506, entitled “Toolset for raising height of nasal sinus.”

Accordingly, various embodiments for a dental implant method and apparatus are described below in the Detailed Description. For example, one embodiment comprises drilling a hole through crestal bone at the top of the socket, dissecting sinus membrane from the crestal bone by pulsing water through the hole and separating the sinus membrane from the crestal bone, then inserting bone mixture through the hole and between the sinus membrane and the crestal bone to increase the thickness of crestal bone. Then, the hole may be bored to a first diameter and a dental implant having threads and a sidecut may be placed in the hole. After the dental implant is placed, gingival tissue may be vertically translated by dissecting the gingival tissue from alveolar bone near to the socket, making lateral cuts in the gingival tissue on the alveolar bone side of the gingival tissue, and translating the gingival tissue so it is adjacent to the dental implant. In this way, a dental implant may be implanted within one surgery.

This Summary is provided to introduce concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
